ABTICL-E-CONTBOLLED y VALVE MECHANISM.

Specification of Letters Patent.

Patented Oct. 3. 1916.

Applloationiled July 26, 1915. Serial No. 41,949.

To all whom z't may concern Be it known that I, ISAAC L. DELANEY, acitizen of the United States, residing at Waynesburg, in the county ofGreene and State of Pennsylvania, have invented certain new and usefulIm rovements in Article-Controlled Valve lv echanism, of which thefollowing is a s eciiication.

This invention re ates to improvements in stoves and furnaces, and morespecifically to article-controlled valve mechanism for gas stoves.

The object of my invention is to provide an article-controlled valvemechanism that may be mounted upon the conventional t pe of gas cockused upon gas s tves with ut very sli ht changes and additions, and at arelative y small cost. Means are provided whereby the placing of acooking utensil over the burner of a stove provided with my device willoperate to turn on the full flow of gas through the valve, whereas theremoval of the utensil will automatically operate to cut off all but avery small ilow of gas. This tends greatly toward economy in fuelconsumption.

Other objects of this invention not at this time more articularlyenumerated, will be clearl un erstood from the detailed description anddrawings forming a part of this specification.

Furthermore, this invention consists in the novel arrangement andcombination of parts more particularly described in the following specication and embodied in the claims appended hereunto and forming a partof this ap lication.

eferring now to the drawing, which is merely illustrative of myinvention, the figure is a side elevation of my device, partly insection, shown in operative relationship with a burner, the openposition being represented in dotted lines.

Referring further to the drawing, wherein similar reference charactersesignate similar parts throughout the respective views, 1 designates anordinary gas cock, provided with a transverse ort 2, adapted to receivea fuel supply pi e not shown), and a fuel regulator 3. e ty e of cock towhich my device is particular y-adaptable is provided with a boss 4,within which is an exhaust port 5. A T-'oint 6 is adapted to be securedwithin the ower portion of said boss, said joint bein provi ed withafuel passageway 7 centra y therethrough. Said passageway 7 is bored toa greater diameter at one end as at 7*, while it terminates in a conicalvalve seat 7* at the other end thereof. A valve stem 8, provided with asuitable packing 9 is adapted to be inserted in said passageway 7, saidpacking 9 being adapted to seat in the larger bore 7 of said passageway.The inner extremity of said valve stem 8 is formed with a substantiallyconical end adapted to form a closure for said valve seat 71. Saidconical end is formed with a iiattened face (not shown) on one sidethere- 0f so that there will'be a small aperture between the seat andthe valve stem when said valve is entirely closed.

A burner 10 of any suitable construction is connected to the valve endof said T- joint.

A right-angularly shaped lever 11 is pivoted centrally of its shorterarm to the casing of said cock l, as at 11 the free end of said shortarm being secured upon one end of said valve stem 8. The longer arm ot'said lever 11V is provided with an offset ortion 12 to which is securedone end of a eaf spring 13, the free end of which engages with the upperface of said cock. A rod 14 is secured near the free end of the longerarm of said bell-crank lever and is vertically disposed at right anglesthereto. A button 15 is mounted upon the upper end of said rod whichextends slightly above the level of the gratin" 16 of a stove and isadapted to be depressedbby a cooking utensil placed thereon.

From the forcgoinar description it is olivious that when a codkingutensil is placed upon the gratin 1G of a stove equipped with my device,the ongcr arm of the lever will be depressed thereby ulling the shorterarm thereof forward. This will operate the valve `stem 8, therebyopening the valve at 7". At all times the poi't 2 is filled with gas andthe flow of the fuel is primarily regulated by the fuel regulator 3.When the vessel is removed from the grating 16 the spring actuated leverwill automatically close the valve at 7, thereby cutting off the flow otgas, excepting that which is permitted to escape throu h theaperturebetween the valve seat and tie valve stein, whereby the gasflame is kept burning in the burner, though with a very small blaze.

The utility, ada tabilit and advanta es of my im roved orm oarticle-control ed valve mec anism for gas stoves being obvious, it isunnecessary to further enlarge upon the same herein.

Having now described and pointed out the new and useful features of myinvention, I do not limit myself to the shape of'certain arts where theshape is not essential nor o I restrict myself to the exact details ofconstruction shown and described, but mean and intend to claim allequivalents and variations thereof not departing in principle from myinvention, and falling within the purview of the appended claims.

What I claim as m invention and desire to secure by Letters atent is:

1. Inan article-controlled valve for stoves, the combination of a mainsupply conduit having an outlet duct, a T-joint connected thereto andhaving a duct communicatin with first said duct a needle valve in one othe arms of said l'l-joint to close communication therethrough, aright-angular lever pivoted on said supply conduit and having an armthereof connected with the needle valve, and article engaging meanscarried by the free end of said lever.

2. In an article controlled valve for stoves, the combination of'a mainsupply conduit having an outlet duct, a T-joint connected thereto andhaving a bore communicating with said duct, a needle valve in saidTjoint,

a right-angularl engaged lever` pivoted on said supply con uit andhaving the shorter` arm thereof connected with the needle valve, springmeans carried by the longer arm to engage the supply conduit and returnthe 1' lever to normal position after an actuation, the free end of saidlever being adapted to en age objects.

n testimony whereof I aiiix my signature hereto.

ISAAC L. DELANEY.
